Objective To discuss the effect of family nursing intervention on the life quality and pulmary function of patients with chronic obstructive pulmonary disease (COPD). Methods We divided 72 patients with COPD into the test group and the control group with 36 cases in each group.The two groups received routine treatment and nursing but additional family intervention was given to the patients and fam-ily members in the test group.The life quality and pulmonary function after intervention in the two groups were appraised in the two groups. Results The evaluation of life quality and pulmonary function were alleviated after intervention compared with those before intervention (P ＜ 0.05).But the above items in the control group were not significantly improved (P ＞ 0.05). Conclusions Effective family intervention could improve the life quality and pulmonary function of patients with COPD.

at model is an ideal MS model for clinical MRI study.

Objective To investigate the effects of probiotics combined with dietary intervention on pe-ripheral blood glucose and lipid metabolism indicators,placental tissue insulin signaling pathway proteins ex-pression and pregnant outcome in the patients with gestational diabetes mellitus(GDM).Methods A total of 83 patients with GDM in this hospital from December 2021 to December 2022 were selected as the study sub-jects and divided into the probiotics group(probiotics combined with diet intervention,43 cases)and control group(simple diet intervention,40 cases)by the random number table method.The levels of peripheral blood glucose,lipid and insulin resistance related indicators before the intervention and in 8 weeks after the interven-tion were compared between the two groups.The histological changes of placenta were observed by HE stai-ning.The pathological indicators were compared between the two groups.The expression levels of insulin re-ceptor substrate-1(IRS-1),glucose transporter 4(GLUT4)and synaptosome-associated protein of 23 kDa(SNAP23)in placental tissue were detected by immunohistochemistry.The pregnant adverse outcomes were compared between the two groups,and the clinical efficacy of probiotics was evaluated.Results Compared with the control group,the levels of fasting blood glucose(FBG),fasting insulin(FINS),serum triglyceride(TG)and low density lipoprotein cholesterol(LDL-C)in 8 weeks after intervention in the probiotics group were significantly decreased(P＜0.05),and the level of serum high density lipoprotein cholesterol(HDL-C)was significantly increased(P＜0.05).There were no significant differences in the incidence rates of poor villi maturation,thickening of dry villi arterioles and capillary filling in villi interstitial between the two groups(P＞0.05).Compared with the control group,the expression levels of IRS-1,GLUT4 and SNAP23 in placen-tal tissue of the probiotics group were significantly increased(P＜0.05).The incidence rates of neonatal hy-poglycemia and neonatal hyperbilirubinemia in the probiotics group were significantly lower than those in the control group(P＜0.05).Conclusion Compared with simple dietary intervention,probiotics combined with dietary intervention has more advantages in improving glucose and lipid metabolism of GDM patients,moreo-ver reduces the adverse events occurrence in newborns.

Objective:To evaluate the effects of the cassette 14C-urea breath test kit, scintillation sampling bottle (solid-state scintillation method) and liquid scintillation 14C-urea breath test kit in the diagnosis of Helicobacter pylori ( H. pylori) infection. Methods:From January 7 to October 28, 2020, 239 patients were enrolled who visited Renji Hospital Affiliated to Shanghai Jiaotong University School of Medicine, the Second Affiliated Hospital of Zhejiang University School of Medicine and the First Affiliated Hospital of Nanchang University. All subjects first received 14C-urea breath test.Within >1 to <7 days after gas collection, mucosal tissues were taken under gastroscopy for gold standard test, including biopsy and rapid urease test (RUT). If both biopsy and RUT indicated H. pylori positive, the result of gold standard test was H. pylori positive, and if both were negative, the result of gold standard test was H. pylori negative. If the results of biopsy and RUT were inconsistent, they were not included in the subsequent analysis. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value and negative predictive value of the cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were analyzed. The safety of the test was evaluated by whether there were any adverse events during the test. Descriptive methods were used for statistical analysis. Results:Among the 239 subjects, 12 cases did not complete the test, 227 subjects finally completed the test. The test completion rate was 95.0% (227/239). No.008 patient was only included in the analysis of cassette 14C-urea breath test kit and scintillation sampling bottle because of lacking the result of liquid scintillation breath test. The results of gold standard test showed that among 227 patients, 87 cases were H. pylori positive, 118 cases were H. pylori negative. The results of biopsy and RUT were inconsistent in 22 cases, so they were not included in the subsequent analysis. Excluding No.008 patient, the results of gold standard test showed that 86 cases were H. pylori positive and 118 cases were negative. Based on the results of gold standard test, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value of cassette 14C-urea breath test kit, scintillation sampling bottle, and the liquid scintillation 14C-urea breath test kit in the diagnosis of H. pylori infection were 91.9%, 100.0%, 96.6%, 100.0% and 94.4%, respectively; 95.4%, 97.5%, 96.6%, 96.5% and 96.6%, respectively; and 96.5%, 99.2%, 98.0%, 98.8% and 97.5%, respectively. Only one adverse event (right upper abdominal pain after eating) occurred. Combined with the patients condition, the adverse event was determined as the onset of chronic cholecystitis and it might not be related to the test medication. Conclusions:Cassette 14C-urea breath test kit, scintillation sampling bottle, and liquid scintillation 14C-urea breath test kit have reliable performance, good safety, and high sensitivity, specificity and accuracy in the diagnosis of H. pylori infection, which are worthy of clinical application.

Objective To study the changes in erythrocyte osmotic fragility(EOF)in patients with hypercythemia,pol-ycythemia and anemia under a high altitude environment.Methods A total of 174 outpatients,inpatients and people un-dergoing physical examination in Tibet Autonomous Region People′s Hospital in October 2020 were enrolled and divided into four groups according to hemoglobin levels:the polycythemia group(n=42),the physiologic increase group(n=48),the a-nemia group(n=29)and the healthy control group(n=55).They were compared with 67 anemia patients and 67 healthy people in the laboratory of Peking Union Medical College Hospital in the same period as the plain control group.The classic EOF test method was used to compare the results of each group′s EOF.The concentrations of NaCl solution for starting he-molysis(STH)and NaCl solution for complete hemolysis(CTH)were included,and the data were statistically analyzed by SPSS software.Results There was a significant difference in CTH between Zang and Han healthy people(P＜0.05).STH in high altitude polycythemia group(0.52)was higher than that in high altitude healthy control group(0.48)(P＜0.001).Compared with plain,the median CTH of plateau anemia group(0.36)and plateau health control group(0.36)was signifi-cantly higher than that of plain anemia group(0.28)and plain control group(0.28)(P＜0.001).Multivariate logistic regres-sion analysis showed that plateau region,female polycythemia and anemia were risk factors for STH elevation.Conclusion This study finds that the EOF increases in the plateau population and patients with polycythemia,which provides reference for studying red blood cell disorders and blood transfusion strategy in the plateau region.

Objective To observe the interventional effects of complex probiotic powder on blood bio-chemical indices and vaginal flora in pregnant women with high risk of gestational diabetes mellitus(GDM). Methods One hundred and ten pregnant women with high risk of GDM recruited from the outpatient clinics of the obstetric department and nutrition department in this hospital were randomly divided into the probiotic intervention group (n=55) and the placebo control group (n=55).The intervention group was given 1 bag of complex probiotic powder per day,and the control group was given 1 bag of placebo powder.The colors,shapes,sizes and tastes of powders in the two groups remained the consistency.The intervention duration in this trial was 23 weeks.The questionnaire survey were conducted at baseline and at the intervention endpoint,and the blood biochemical indexes detections were performed at baseline,after 24-28 weeks of gestation,and after 34-38 weeks of gestation,respectively.In addition,the differences in the composition of the vaginal flora structure between the two groups of high risk pregnant women with GDM were detected at the intervention endpoint.Results A total of 97 cases were eventually included in the statistical analysis.Among them,there were 50 cases in the probiotic intervention group and 47 cases in the placebo control group.At the end of the 23 week intervention,there were no statistically significant differences in fasting blood glucose,red blood cells,hemoglobin,leukocytes,ferritin,total protein,albumin,glutamic transaminase,glutamic oxalate transam-inase and total bilirubin between the probiotic intervention group and placebo control group (P>0.05).In terms of vaginal flora,there was a significant difference in some indicators of α diversity between the probiotic group and placebo control group (P<0.05),and there was no significant difference in β diversity between the two groups (P>0.05).At the level of vaginal flora phyla,there were significant differences in the Firmicutes,Actinobacteria,Desulfobacterota,Deferribacterota,and δ-Myxococcota between the two groups (P<0.05).At the level of vaginal flora genera,the relative abundance of Lactobacillus spp.in the probiotic intervention group was significantly higher than that in the control group (P<0.05).Conclusion Complex probiotic pow-der supplementation may have a limited role in improving blood glucose and other related biochemical indica-tors in high-risk pregnant women with GDM.But it has a certain role in regulating the vaginal micro ecological balance in pregnant women with high risk of GDM.
